Grout Additive
Grout additives are polymer-based liquids used as a replacement for mixing water in cementitious tile grout formulations, improving flexibility, stain resistance, and chemical resistance of the cured grout joint. They reduce water absorption of grout joints in wet areas such as showers, kitchens, and swimming pools, preventing mold growth and discoloration. These additives are compatible with standard sanded and unsanded grout formulations and help achieve CG2 classification per EN 13888.
